There's nothing in the hardware that prevents systems from keeping most components in low power mode while others are still active. And likewise there's no reason for software to prevent it either. In fact I'm totally at a loss to understand why you have such a strong objection to the idea. There are any number of embedded systems that rely on selective suspend and resume -- along with other power management techniques! -- to minimize power drain. Why should Linux cripple itself by ruling out such techniques? Penguins with just one flipper havea hard time swimming ... :) - Dave
